Phuket, TsunamiMy friend's friend, diving teacher, he worked as normal on that day...
Deep in water, suddenly all fish around gone, damn dark
Floated up to water surface, everything were swept away
People in deep water were not affected by the Tsunami, because the wave came from sea surface? I dono the reason, but the story is true...
discovery曾经放过一个关于tsunami的片子
tsunami和普通波浪的区别在于它的波长很长,所以能量很大。普通波浪波长之多100米,但是浪高可达10几米;而tsunami的波长可达上百公里,即便peak有10几米,在open sea也看不出来有什么不一样。只有进入bay之后,由于海面越来越窄,浪越推越高,而且一个波浪就有几十公里长,全部冲上岸,破坏力是惊人的。印度洋海啸时,当时海面上船只没有太大问题,问题全部出在海岸线一带。
至于在水下,我想他们只能感觉到水流,而感觉不到海浪的。
